Question

A 1.0 kg object is attached to a string 0.50 m. It is twirled in a horizontal circle above the ground at a speed of 5.0 m/s.

The direction of the acceleration at the point shown points toward which letter? (5 points)


A

B

C

D

Answer 1

D.

Step-by-step explanation:

Answer 2

Answer: d

Step-by-step explanation:

For an object to move in a uniform circular motion, only force that acts on it is the centripetal force which acts along the line joining the object and center of the circular path. The acceleration also acts in the direction of force. The centripetal acceleration acts along the radius of the circular motion path.

In the given horizontal circle, the direction of the acceleration of the object points towards d.
